Multijet Background Estimation with the Rebalance and Smear Method — Arthur Linß1, Xuanhong Lou1, •Jonas Neundorf1, Krisztian Peters1, Matthias Saimpert2, and Christian Sander1 — 1DESY — 2CERN
In analyses without leptons in the final state, the multijet background can become relevant. For this talk, the implementation of the data-driven Rebalance and Smear method for multijet background estimation was modified in order to make it usable for different analyses. It is then applied to searches for new physics in the tt + ETmiss channel. The data-driven estimate is shown to agree with the expectation from Monte Carlo simulations and, combined with the Monte Carlo expecations of other background processes, the data yield in the validation regions.
